                    <option value="Triple Jump">Triple Jump</option>
                    <option value="4x100 Metres Relay">4x100 Metres relay</option>
                </select>
            </div>
            <input type="button" id="addEvent" name="addEvent" value="Add Event" />
        </fieldset>


    </form>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
    <script src="newButtons.js"></script>
</body>

该HTML使用jQuery创建带有下拉菜单的菜单集，然后使用按钮创建另一个事件，如下所示：

jQuery(function($){
var $button = $('#addEvent'),
    $row = $('.newEvent').clone();

$button.click(function(){
    $row.clone().insertBefore( $button );
});

}）;

我想在右上角添加一个用于创建/显示字段集的按钮，以便每次单击它都会创建一个新的字段表。同样，当该站点首次启动时，将不存在任何字段集，并且在出现该字段之前必须先按下右上角的按钮。

创建字段集的按钮
